I have a few issues with your plugin which on the whole I have found to be better than many others I tried. My site is http://www.amwphotos.co.uk/wp/ and I'm gradually setting all my 'featured images' to open as a thickbox.
1. Neither Title nor Caption appear on the image.
2. Each image appears twice in when clicking previous next, presumably because I am using 'Page links to' so it recognises the link and image, but if I disable the auto thickbox feature they just load as an image not in a thickbox.
3. 'Single image' and 'Gallery images' both show all photos on the page.
4. How can I change the appearance of 'Modified thickbox' so that it looks like the 'built in thickbox' but has the fade in effect of the former.
A lot of questions I know, but probably stuff that many people have tried to sort out.
Thanks in advance.
